11. that portion of photosynthesis that requires light energy
12. the anaerobic breakdown of sugars to pyruvate and then to either lactic acid or carbon dioxide and alcohol
13. the process by which cells break down glucose or other nutrients to produce usable energy

1. the first phase of cellular respiration, in which glucose is broken down into pyruvate
3. material within a chloroplast that surrounds the thylakoids
5. that portion of photosynthesis that does not require light energy in order to process the light-independent phase but neither phase occurs during darkness
6. the second phase of aerobic cellular respiration in which pyruvate reacts with enzymes to produce acetyk CoA, carbon dioxide, hydrogen ions, ATP, and electrons
7. a flattened membranebound sac inside a chloroplast where the light independent phase of phtosynethesis takes place
